The simplest format in ultrarunning and the hardest to survive. There is no distance to reach and no overall time limit — only the next bell, and then the one after that. Places are allocated through a combination of LSU team selection and a random draw: request a race entry for an open event.
Everything else is a detail.
On the hour, the whole field leaves the same corral.
No staggered starts, no seeding. A first-timer sets off next to a national record holder.
One loop is a yard. Be back before the next bell.
You have until the hour turns to finish the loop and stand in the corral, ready to go again.
No grace period, no appeal — at yard 3 and at yard 93.
Not in the corral when the hour turns, race over. However far you had come.
Nobody knows if this is one night or four.
The winner finishes one yard nobody else can. If no one manages it, there is no winner and everyone is a DNF.
Eating, sleeping and kit all come out of the hour you just ran in.
A marked 3 × 3 metre square for a race with no known end.
Season 2, 2026: 160 started, one was still there four days later. Season 1 ended at 67 yards, the world record stands at 119.
